C280 dots all over prints

[copier tech]

I hope someone can help, no idea what causes this. It prints the gradation prints perfecty, all other copies or prints have these dots!

i've tried updating the firmware.

I thought the laser but it prints gradation pattens ok.

Has this machine gotten reset , initialized, or a new NVRAM???

MFP board or ram.

try the ram first, if no go, mfp, problem solved.

Try set it up as if it was new machine.

C360 have a nasty habit of their mfp's failing for no reason. I havent had those same dots, but train tracks and other image distortions on a couple and it has always taken a mfp board

I think the initial setup lines are different than those, i think they are solid bars. but it will display them if its been reset or somtehing. to get rid of those lines you have to run through the initial setup again, doing touch panel adjustment < a couple more things> and ending with the gradation adjustment.

Thanks for all the info, I don't feel it's an initial install type fault as the lines look different, I did however go through the setup anyway. I have another c280 I can take an MFP from, i'll try the ram first. If I do fit a used MFP board will I loose all the machine/customers settings, IP, address book etc? If so I guess I can import/export those settings. Also fitting a used MFP board will I get that license management error message!?

Hi, you can keep the mfp and the nvram together from your other machine to try to diagnose the fault on this machine, you will get licence man error, but this way if the fault is not the mfp you can refit the original without the management error, if you find that the mfp is at fault and fit the mfp from the other machine make sure the firmware level is the same otherwise you will end up having to format the hdd, then you will lose your scan settings, otherwise you should only get the licence management error, which is easily fixed by obtaining a repair code from konicas LMS.

If I fit the MFP from my good machine, can I use the NVRAM from the faulty c280, or is it best to keep the NVRAM on the original MFP boards?
Can I avoid the licence management error? what boards do I swap from my working c280 to my faulty C280, how about counter readings, will they change over? sorry for all the questions but I'm looking for a the quickest & simplest fix!

Counters, machine settings and hard drive format key are on the nvram among other stuff. it should stay with the machine it came with.

If you want the easiest fix of all use a brand new mfp board, drop it in, update firmware and away it goes.
